Microsoft is finally waking up to what we’ve all been saying since before Windows 10 was released: forcing operating system updates on users is not a good idea. Amusingly, they are presenting their findings and announcing related changes as if these things were previously unknown to the world of computing.
Microsoft refers to the process of installing Windows updates as an ‘experience’, and uses adjectives like ‘great’ when describing what they want the experience to be like for users. I don’t know about you, but I’ve never thought about installing updates as a ‘great experience’. Nightmarish, never-ending, endurable, and dreaded are more familiar ways to describe my update experiences. The word I’d most like to use in connection with updates is ‘uneventful’.
Note: phrases like ‘great update experience’ were no doubt vetted by some Microsoft committee. Microsoft writers are presumably encouraged to use these phrases, and avoid negative terminology.
Microsoft still seems unable to understand what people actually want to ‘experience’ from a Windows update:
We don’t want updates at all, really. We want software to not be full of security holes in the first place. But that’s a fantasy, and will never happen (sigh).
We want updates to not cause problems. Ever.
Updates should install quickly, and with minimal fuss. Giant downloads, massive storage requirements, lengthy update durations, and high CPU usage are unacceptable.
It should be possible to easily, quickly, and effectively revert updates.
Automatic updates are a nice option, but only if we have full control over when they occur.
Upcoming Windows Update changes
Download and install now option: a new option on the Windows Update page that installs ‘feature updates’, which provide new or improved functionality. Using this option effectively updates Windows 10 to the latest version in terms of features, without installing any bug or security fixes. According to Microsoft, it’s a way to get the latest features without installing anything potentially risky.
Extended ability to pause updates. This further extends your ability to delay installation of updates, although it’s still limited: you can delay an update up to 35 days (seven days at a time, up to five times). This one is important for Windows 10 Home users, because the feature was previously unavailable on that version.
Intelligent active hours. The ‘active hours’ setting, which was added in the Anniversary Update, allows you to specify a window of time during which updates should never occur. This will now adjust itself automatically, based on when it thinks the computer is actually being used. This sounds good, but in practise, it may cause more problems than it solves. We’ll see.
Improved update orchestration. This new feature will detect device usage, and attempt to install updates when utilization is low, such as when there is no user activity.
These are all welcome changes, but I’m hoping Microsoft goes even further. If the Windows 10 update process improves enough, I may even consider installing it again. For now, there are still too many problems, such as Windows Update’s excessive use of disk space.
At least Microsoft is listening to the complaints about update dialogs popping up over important presentations, and worse. And they’re being surprisingly transparent during this current round of Windows improvements. Several recent Windows update disasters (like this one) were probably the main impetus behind the changes, though.
You know, it’s theoretically possible that we could get a Patch Tuesday with no updates to install. We’ve had months like that for Adobe products. Not for Microsoft, though, at least not in my memory.
Anyway… this month from Microsoft we have thirty-four updates, addressing seventy-five security vulnerabilities in Internet Explorer, Edge, Flash in Microsoft browsers, Office, and Windows. At least that’s what my analysis shows. The source of this information, Microsoft’s Security Update Guide, is a complex beast.
Reminder: these updates are only for versions that are still supported. Windows XP is no longer supported, and Windows 7 won’t be for much longer. Versions of Office older than 2010 are no longer supported, and Office 2010 support will end later in 2019.
It was a busy month for Adobe, with updates to Flash, Reader, and Shockwave.
If you have an email address, and you’ve ever used it to register for online services and sites, there’s a good chance you’ve received email that threatens you in some way, and some of it is downright creepy.
This email may refer to your name. It may include a password you’ve used in the past, or even currently. The email may appear to have been sent from your own email address, and may claim to have taken over that email account.
The good news is that very little of what these emails claim is actually true. The bad news is that you still have a problem.
But why does this happen?
It all starts when someone gets careless, or someone else decides that the IT budget is too high.
Imagine that you’re the person responsible for information security at any company that… uses computers (so basically, any company on the planet). Now imagine that you’re bad at your job. Or disgruntled. Or your manager keeps cutting your budget. Inevitably, things start to slide. Security updates don’t get installed. Software that isn’t properly checked for security implications gets installed on company computers. Users don’t get security training. Bad decisions are made, such as not properly encrypting user passwords. And so, the company’s computers, and the data they contain, become vulnerable. Eventually, malicious people figure this out, and through various means — many of which are trivially simple to carry out — gain access to your data. And that data includes information about your customers. That information is then sold online, to other, even less scrupulous people. Brian Krebs documents many of these breaches; here’s one example.
You can find these lists online if you know where to look. Some are only accessible from the dark web. Some are published more brazenly, on easily-accessed public web sites, including Facebook.
Sometimes these lists contain passwords. In really awful cases, the passwords aren’t even encrypted. But usually they are encrypted, which makes them slightly less useful. Only slightly, because many people still use terrible passwords: common passwords, like 1234; passwords that are used by the same person in multiple places; and passwords that are easy to crack.
Any password can be cracked, by which I mean converted from its encrypted form to its original, unencrypted form. Short and simple passwords can be cracked in nanoseconds. Longer, more complex passwords take longer. At any given point in time, passwords that are long and complex enough simply can’t be cracked quickly enough to be worth the attempt. This is a moving target. As computers get faster, the point at which a password becomes worth cracking gets nearer.
These shady lists of users, passwords, and email addresses can be used for lots of things, ranging from merely irritating to criminal. But there’s money to be made, as long as you don’t care about being a world-class asshole.
If you’re an asshole, and you’re looking for an easy way to make money and irritate people, just shell out a few bucks for one of these lists, and download a few scripts that turn that list into spam. Because computers are really good at things like this, you hardly have to do any actual work. Just feed a list into some crappy script, sit back, and watch the money pour in. If you had to do this with paper and snail mail, it clearly would not be worthwile.
A user’s story
Let’s look at this another way: from the perspective of Iam Notreal, an ordinary Internet user. Iam registered for an account at LinkedIn in 2011 using his real name and his NopeMail account, firstname.lastname@example.org. He also used the same password he uses everywhere else: banana1234.
In 2012, intruders gained access to LinkedIn servers and were able to download its user database. The database included usernames, email addresses, and poorly-encrypted passwords. Now Iam’s real name, real email address, and an encrypted form of his one and only password are on a list, and, beginning in 2016, that list is being sold on the dark web to anyone who has a few bucks to spare.
In 2016, Iam starts getting spam to his NopeMail account. Most of it is ordinary spam: poorly-worded appeals to click a link. Occasionally he receives spam that mentions his real name, which is alarming, but not particularly harmful. At some point, Bill tries to ‘unsubscribe’ from what he believes is a mailing list, by replying to one of these spam emails. Congratulations, Iam, you’ve just graduated to a new list, of confirmed, valid, active email addresses. This list will also be sold on the dark web, at a higher price than the original list.
Meanwhile, other dark forces are at work behind the scenes. Someone runs the original list through a widely-available password cracker. This software looks at each encrypted password and attempts to decrypt it based on a set of parameters, including lists of commonly-used passwords. Sadly, Iam’s password is rather short, and contains a common word, and it takes the software about a nanosecond to crack it. Now Iam is on an even more valuable list, which includes cracked passwords.
Fast forward to 2018, and now Iam is getting email that claims to have taken over his email account, or to have video from Iam’s own webcam showing him doing unmentionable things, and it also includes Iam’s one and only password, right there in plain text. Iam is panicked: if the sender knows his password, are the rest of the claims true? He doesn’t know it, but the sender’s claims are bullshit.
As scary as this sounds, it’s only the most common use of lists like these circa late 2018, early 2019. The same information could be used to take over Iam’s LinkedIn account (if he ignored warnings from LinkedIn to change his password, or if he changed it back to the same password), take over his NopeMail account (if he failed to change its password after the LinkedIn breach), or take over any other account that can be found on any other service he uses, once it’s discovered.
Why is that spam coming from my own email address or my own mail server?
Unfortunately, it remains trvially easy to spoof almost all information contained in an email message. Current anti-spam efforts like SPF, DKIM, and DMARC are focused on validation, and there’s nothing stopping anyone from spewing out email with mostly-forged headers. That includes the FROM header, which means scammers can make email look like it came from just about any address they want. Only close inspection of all the headers reveals the actual source.
Why does that spam contain my password?
If a scammer has access to a purloined user list that includes plaintext or cracked passwords, it’s a simple matter of customizing the content of their malicious spam so that the username and/or password vary, depending on the unlucky recipient.
What you should do
Stop using crappy passwords. If you’re not sure how crappy your password is, check it at howsecureismypassword.net. You can also install this extension in your Chrome browser; it will warn you if your password is too weak.
Stop re-using passwords. If site A is hacked, and your password for site A is the same as for site B, you’ll have to change your password on both sites.
Use a password manager. Yes, it’s annoying to have an extra step whenever you want to log in somewhere, but using a password manager means that you only ever have to remember one password. They can also generate passwords for you, saving you the trouble.

Although there are ways to use purloined user lists besides spam, most of the damage we see is related to email.
Despite being really old technology, email has continually improved in terms of security. Newer technologies like SPF, DKIM, and DMARC make it much easier for email providers to determine which email is legitimate and which is not.
You can help by making sure any email domains you manage use SPF, DKIM, and DMARC. If your mail provider doesn’t use these technologies, lean on them to start. If they resist, find another provider. I have several clients who use the business mail service provided by telecom giant Telus here in Canada. Telus farms this work out to a provider in the USA called Megamailservers. The Megamailservers service does not currently support DKIM or DMARC, and there’s nothing on their web site (or that of Telus) about any plans to change that.
Password Management Software
So, everyone should use a password manager. But wait, didn’t I just read that all the most popular password managers can be bypassed very easily? Yup. Opinions vary as to whether the risk of such exploits is significant. From my perspective, the risk is this: yes, a malicious actor needs physical, remote, or programmatic access to your computer to use these exploits. But once they have access, they no longer have to waste time looking for interesting information. All they need to do is look for password manager data and sent it to themselves. That makes their job MUCH easier.
But using a password manager is still much safer than not using one.
When you have a lot of tabs open, Firefox now shows a down-arrow button at the end of the tab bar. Clicking this button shows a list of all open tabs, and provides a special search function, allowing you to search your open tabs.
Scroll Anchoring tries to keep your content in place even as advertising and other images try to push what you’re reading off the page.
You can check which version you’re running by clicking Firefox’s ‘hamburger’ menu, and navigating to Help > About Firefox. If you’re not yet up to date, you should see an Update button that allows you to install the latest version.
Many of the vulnerabilities addressed in Chrome 73.0.3683.75 were discovered by external security researchers, once again demonstrating the value of Google’s open attitude towards bug submissions.
Although Chrome usually updates itself within a few days of a new release, you can expedite this process by checking for available updates. Do that by navigating Chrome’s three-dot menu (by default at the top right), to Help > About Google Chrome. This will trigger an update, if one is available.
A security update in the Chrome engine prompted last week’s release of Opera 58.0.3135.90. Opera is built on Google’s Chrome engine (also known as Blink), so when there’s a security update in Chrome, it usually finds its way into Opera within days.
Aside: The Blink engine forms the core of many popular browsers. I use Chrome, Vivaldi, Opera, Firefox, Internet Explorer and Edge for different tasks, based on my experience with those browsers. Opera, Vivaldi, and of course Chrome are built on the Blink engine. Internet Explorer is being phased out. Edge will soon be built using Blink instead of Microsoft’s own engine. The Blink engine seems poised to take over completely, which has some people concerned.
To check Opera’s version, click its ‘O’ menu (usually at the top left), then select Update & Recovery, then click Check for Update.
According to Microsoft’s Security Update Guide, March’s updates, twenty-eight in all, include fixes for at least sixty-five security vulnerabilities in .NET, Flash Player (in IE and Edge), Internet Explorer, Edge, Office, Visual Studio, and Windows.
Even if you have automatic updates enabled on Windows 7 and 8 computers, it’s a good idea to check for and install the new updates. If you’re running Windows 10, auto-updates can’t be disabled, but you can still check for updates, and get them sooner that way.
There are no updates for Flash or Reader from Adobe so far in March.
The latest Chrome browser release is version 72.0.3626.121, and it fixes a security vulnerability for which exploits have been observed ‘in the wild’. So this is an important update.
When I try to look at the full change log using the link provided by Google, I get a blank page. Not sure what’s going on there.
If you use Chrome, it’s almost certainly updating itself on Google’s somewhat mysterious schedule. But you can check your version and initiate an update by navigating its ‘three dot’ menu to Help > About Google Chrome.
Although there are several variations of Acrobat and Reader, the one of interest to most people is the freeware Acrobat Reader DC (Continuous). That’s the one you probably have installed on your computer. The new version for that variant is 2019.010.20098.
Recent versions of Reader seem to update themselves in the background, courtesy of an update service called ARM that gets installed along with Adobe products. You can check which version you’re running by navigating Reader’s menu to Help > About Adobe Acrobat Reader DC.
News for me, stuff that matters… to me. Windows, Linux, security, tools & miscellany.
